The Challenge

  • The initial project requirement was to deliver and set-up a 26,750m² shoreside support base that could facilitate, at its peak, up to 350 onshore and offshore personnel either working onsite or passing through.
  • Other responsibilities as OSC included the provision of both crew transfer vessels (CTVs) and guard vessels, a range of personnel and a complete marine service package.

The Solution

  • As OSC, JF Renewables offered an integrated solution to provide a range of onshore and offshore services with in-house support from group companies.
  • The marine service package provided covered a range of scopes, including:
    • Marine coordination
    • Offshore and onshore communications
    • Vessel refuelling and bunkering
    • The provision of offshore temporary power
    • The provision of standby diving
    • ROV and unexplored ordinance (UXO) solutions
    • The provision, installation, maintenance and demobilisation of demarcation buoys
    • Vessel mooring solutions and emergency response services
  • Integrating the project further, JF Renewables supplied four CTV vessels, two guard vessels and its specialist project support vessel on an ad hoc basis.
